HVACTemplate:Zone:IdealLoadsAirSystem tries to make things simple for you and it automatically creates a ZoneControl:Humidistat object which is causing the duplicate humidistat error. You can see this by looking at the expidf output file.

If you have fixed humidity setpoints, then put these values in the HVACTemplate:Zone:IdealLoadsAirSystemfields for "Humidification Setpoint" and "Dehumidification Setpoint", and delete the ZoneControl:Humidistat object in the idf.

If the humidity setpoints vary, then you'll have to abandon HVACTemplate and use native objects. The simplest solution is to take the expidf output from this file (it will be useful even though there are errors), rename it to <newname>.idf and delete the extra humidistat object(s).
